Headset Microphone not working.

Hello,
I purchased a razer carcharias gaming headset around four months ago with the purpose of using it for gaming as well as as a general pair of headphones for my computer. Yesterday, while I was using it on a skype call, the microphone just stopped working. After going into my computers microphone settings, I have learned that the microphone IS being recognized, but not picking up any voice.

I just need help, because I am not sure if this is a hardware problem, or a problem with the computer itself.
